Beschreibung
Zusammenfassung:	The present invention relates to a method of inkjet printing comprising the following steps, in order: (i) providing a substrate; (ii) jetting a primer onto the substrate, wherein the primer comprises one or more monofunctional monomers, a passive resin and one or more photoinitiators, wherein the one or more monofunctional monomers are present in at least 85% by weight, based on the total weight of the primer; (iii) jetting an inkjet ink onto the primer, wherein the inkjet ink comprises one or more multifunctional monomers, a colourant, one or more photoinitiators and optionally one or more multifunctional oligomers, wherein the total weight of the multifunctional monomers combined with, when present, the multifunctional oligomers, is at least 15% by weight based on the total weight of the ink; and (iv) curing the primer and the inkjet ink. The present invention also provides a printed substrate obtainable by the method of the present invention, a primer as used in the method of the present invention, and an ink set comprising a primer as used in the method of the present invention and an inkjet ink as used in the method of the present invention.
